Can't interop with subkey

Guys, I’m driving myself crazy and I hope you can help me out.

If I sign a message with @polkadot, I can’t then verify it with subkey, how does that work?

// Output:

const { sr25519PairFromSeed, sr25519Sign, cryptoWaitReady } = require('@polkadot/util-crypto')

cryptoWaitReady().then(() => {
    const pair = sr25519PairFromSeed(Buffer.from("42f2524bd7800cc244deb8ce5b4c24cb262c1ba317b86880d7ff33f1e93c6348", 'hex'))

    console.log(Buffer.from(pair.publicKey).toString('hex'))
    console.log(Buffer.from(pair.secretKey).toString('hex'))

    console.log(Buffer.from(sr25519Sign("test message", pair)).toString('hex'))
})

From subkey:

For context

I got here because I am getting an error 1010 when submitting a balance transfer to Westend. I then found these two but I didn’t manage to get anywhere either. This code still fails:

const CTX : &'static [u8] = b"substrate";
let sec = SecretKey::generate();
let pub_bytes = sec.to_public().to_bytes();

let message = b"<Bytes>message to sign</Bytes>";

let sig = match (SecretKey::from_ed25519_bytes(&sec.to_bytes()), PublicKey::from_bytes(&pub_bytes)) {
(Ok(s), Ok(k)) => s
	.sign_simple(CTX, message, &k)
	.to_bytes()
	.to_vec(),
_ => panic!("Invalid secret or pubkey provided.")
};


// ext_sr_verify function
let res =   match (Signature::from_bytes(&sig), PublicKey::from_bytes(&pub_bytes)) {
(Ok(s), Ok(k)) => k
	.verify_simple(CTX, message, &s)
	.is_ok(),
_ => false
};

assert!(res)
